Sesia-OPERATING DEVICE.

Specification of Letters Patent.

Patented Mar. 11, 1913.

Application led September 20, 1909. Serial No. 518,488.

vTo all wiz-0m t may concern .Be it known that I, ANDREWS ALLEN, acitizen of'the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Sash-Operating De of which the following is a specification.

This invention relates to means for operating and locking easementwindows, screens, shutters, and the like, and has for its object toprovide a device which will enable a easement window, or other sash orshutter hinged at one edge, to be opened by a direct outward thrust; toprovide an operating mechanism which will beread-ily adapted to easementwindows of the like where screens,y when employed, are necessarilyplaced on the inside of the hinged sash; and to provide an operatingdevice which will automaticallyv lock the window and also the screenwhen in the closed podv sition. To accomplish these and other desirableadvantages which will appear in connection with the particulardescription of the invention, I construct the operating mechanism in theform of a jointed bar, the joints being of unequal length, the shorterone having a pivotal connectionwith a'n attaching member or bracket forsecurement to the sash, and the longer one having its inner endpreferably fashioned. to provide a finger hold and guard. Both membersof the operating bar are preferably provided with perforations for thepassage of alockin pin. A guide member or keeper is a apted to besecured to the window sill and is provided with a guide slot throughwhich the operating bar reciprocates, and with a vertical perforationfor the locking pm.,

In the accompanying drawings-Figure 1 is a sectional elevation throughthe lower portion of a easement window, a screen, and the window silland water table, showing the operating device in sideV elevation and inclosed and locked position, and also by dotted lines in open position; Fig, 2 is a perspective view of the device detached from the window; Fig.3 is a sectional detail plan View of the guide keeper and operating bar,the latteivbeing broken away, the dotted lines showing differentpositions of 'the bar Fig. 4 is a transverse sectional view through theWindow sash, screen, one side frame, the sill, water table, theoperating devlce show- Iing in plan view; Fig. 5 is a detailed viewshowing a modification in the construction of the hinge joint of thelookin bar; and Fig. 6 is a fragmentary view o the upper end ofthescreen showing a hinge therefor.

In the drawings, 7 indicates the lower frame bar of a easement window.

Sindicates the window sill and 9 the water table. y v,

10 represents the frame of a ily-screen and 1l one of the hinges wherebythe screen is suspendedfrom its upper end.

It will be understood that the window may be hinged at one edge as shownat 12 (Fig. 4);

Usually in easement windows the sill is very narrow and the spaceallowed for the mounting of the window sash and the screen isrestricted; therefore, it is important to provide an operating means forthe window sash which is adapted to these narrow limits;

My improved operating device is shown complete in Fig. 2, wherein 14 and15 represent two plates constituting a guidekeeper, and whichas shownareformed separately for convenience of construction, but which might bemade integral. The member 14 has an upstanding flange 14a and a hori-,zontal shelf-like portion 14h.' The flange 14 isparted at its middle topermit the passage of the operating bar, the parted portions 14 beingarranged at an angle and converging" rearwardly to constitute ,guidesfor the op erating=barg on the extremities of the por tion 14 theoperating bar fulcrums Whenfthe window is opened wide. The keeper may beattached at either side of the window. The shelf-like port-ion 14h andthe base member 15 have registering perforations for a locking pin 16and other perforations 14d for fastening screws'. The operating bar iscomposed of two members 17, 18 hinged together by a pin 19, the member18 having a knuckle 18, as shown in Fig. 2. This knuckle may, as shownin Fig. l5, be extended, the slot in the member 17 being correspondinglylengthened, so that the extension will abut against the edge of theshelf 14", thereby affording a lock for the screen and vWindow whenclosed and t-he member 18 falls into vertical position as indicated inFigs. 1 and 2. The outer' end of the member 17 is pivotally connected tothe bracket plate 20, which will be secured 'by means of screws to thebottom bar 7 of t-he Window the extent of piece 18b example, by

sash. The keeper projects beneath the screen, the lower bar 10 of whichmayfbe out away to permitits passage.

With the parts constructed and arranged as above described, the windowsash may be opened and' locked in any desired posi-y tion ofadjustmentby a straight thrust of the operating bar, and the latterduring the early part of itsJ movement being extended in a straightline. When movedto the full extent the bar will assume angular positionssuch as indicated by the dotted lines in Fig.y

3, the degree of angularity depending upon the movement; but the bar is'operated by a 4straight thrust and is guided by the members 14Cc at alltimes regardless of the extent of the mor/ement. -Thebar is locked intheattain'e'd position by the insertion of the pin 16 through theaperture of the base plate inside of the screen, ing pin passing throughone of .the apertures of the bar 18.' This bar is preferably provided atits free" extremity with a finger and a guard 18c affording convenientmeans both for moving the bar and protecting the fingers against injury.Theseparts may be formed in other ways, as, for

circular form.A Whenthe member 18 is in the pendent position indicatedinrFi'gs. 1 and 2, the device' would be locked since it would bedifficult to apply sufficient orce from the outside to `raise thisdepending member anddraw'it through the keeper. `IA

Y Jointing the operating rod has several ad vantages, as follows: Thedevice' may `be adapted to windows of anyI w dierent widths of sills;the rod when Very long would be objectionable because it would be in theway if made in a single piece; and by jointing the rod the inner memberaffords an efficient lock.-

for example, in the pin in the ioekbending the. end 'of the bar to widthand.k to

remesa Obviously, structural variations may be made within the scope oflmy invention, as, proportional length of the two' members of theoperating. bar; in the specific character of the locking pin andperforations; and in the form of the guide. The guide may becountersunk. in.the window sill or covered4 by af false sill-.to avoid.cutting the screen sash.

I claim: 4

1. In a window sash Voperating device, the combination of a jointedoperating rod having a plurality oi locking apertures therein, a guidemember having an to register with anyl of saidrodapertures, a two ofsaid registering apertures whereby said` rod and vguide member arelocked together, and a pair of guides proper constituting part of saidguide member having free edges., contacting opposite sides of said rodin a vertical, plane substantially through said pin, whereby said pinalone holds said rod inlockedposition and wherebya close slidingconnection is maintained between said guides proper and said rod invarying angles of the rod, substantiallyvas described.

2. In 'a window sashoperating device of the class described,- .thecombination ,of an operating rod, a guide member, said guide memberhaving an end portion comprising a -base and a 4cover and'an upstandingwall between said base and cover, said wall being divided l centrallyand the divided parts thereof'bent apart to form guides prop r, said rodbeing in sliding'contact with t e edges of saidj guides proper, saidbase and Vaperture adapted cover portions having registering aperturessubstantially `in the Vertical plane oi'El the ends of said guidesproper, said rode-having 96 engagement with saidrod to take up wear,

and whereby said guides Iproper are :Ere'e frombinding action ofisaidrod, substantiallyas' described'. ANDREWS ALLEN. Witnesses:
